2020 Subaru Impreza CV Boots — What They Do and How to Look After Them

CV boots are absolutely relevant to the 2020 Subaru Impreza. Subaru’s 2020MY Impreza Service Manual (Drive Shaft/Front and Rear sections) specifies constant velocity joints with rubber boots on both front and rear drive shafts, and the Subaru Genuine Parts Catalogue lists replacement CV boot kits for this model. Those technical references confirm the vehicle relies on CV boots to protect each CV joint, essential on the Impreza’s full-time AWD driveline.

What do they do? Each CV boot is a flexible rubber bellows that seals in high-moly grease and seals out water, mud, and road grit. That lets the joint run smoothly while the wheels steer, the suspension moves, and torque is sent to the tyres. On an AWD Impreza, the boots cop plenty of movement and heat, so keeping them intact is key to avoiding premature joint wear, clicking on turns, and vibration under load.

Maintenance is simple but important. During routine servicing, the boots should be checked for splits, perishing, loose clamps, and any grease fling on the inside of the wheels or under the guards. If a boot is just weeping or the rubber’s looking tired, a proactive boot replacement can save a far pricier driveshaft. If it’s torn and the joint’s been contaminated or is already clicking, the smarter call is often a complete shaft replacement.

• Inspect at every service interval and after rough-road or beach trips.
• Look for grease spray, cracking, or damp spots around the boot ribs and clamps.
• Act fast on tears—grit and water can ruin a CV joint in a few hundred kilometres.
• Use genuine or OEM-quality boot kits with the correct grease and crimp bands.

For replacement, proper tools matter: correct banding pliers for clamp tension, careful cleaning, and the right grease volume as per the workshop manual. Avoid “split” quick-fit boots on this car, they rarely last. Front boot replacement often takes 1–2 hours per side in workshop conditions. A road test afterwards is a must to confirm no noise or vibration, and the axle nut should be torqued to spec from the service manual.

Popular questions about 2020 Subaru Impreza CV boots

How long do CV boots last on a 2020 Impreza?
With regular servicing and road use, factory boots commonly last well beyond 100,000 km. Heat, coastal exposure, gravel, and lowered or lifted suspension can shorten their life. A quick look at each service helps catch issues early.

Can someone drive with a torn CV boot?
It’s best to avoid it. A fresh tear lets grease out and grit in, and a good joint can be ruined quickly. If the joint isn’t clicking yet, a prompt boot replacement may save the shaft. If noise has started, plan on a full driveshaft replacement.

Boot or whole shaft—what’s the better fix?
If the boot has only just failed and the joint is quiet and clean, a new boot kit is cost-effective. If there’s clicking on turns, rust in the grease, or heavy wear marks, replacing the complete driveshaft is the reliable long-term solution.
